Referring to fig. 7 and 8, the power supply module comprises a solar photovoltaic panel, the solar photovoltaic panel is connected with a charging control circuit through a voltage stabilizing circuit, the charging control circuit is connected with a super capacitor, and the super capacitor is connected with the clock movement control MCU.
As shown in fig. 7: the solar photovoltaic panel wiring terminal 12 is connected with an overvoltage and overcurrent protection and input filter circuit 13, and the overvoltage and overcurrent protection and input filter circuit 13 is connected with a voltage stabilization output circuit 14 through a voltage stabilization chip U1.

In the charging current limiting circuit 22, the charging maximum current of the super capacitor is set according to the resistance value of the resistor R6.
When the sunlight intensity is insufficient or under the condition of a dark environment, the output voltage of the solar photovoltaic panel is lower than the threshold value of the starting working voltage of the voltage stabilizing circuit, the EN end voltage of the voltage stabilizing chip is at a low level, the voltage stabilizing chip U1 is closed and does not work, the voltage POWER is 0V, the charging control chip U2 is also in a closed state, and Vout for supplying POWER to the clock movement control MCU is directly provided by the super capacitor.

In a normal travel state, the clock movement control MCU sends a control instruction every 30 seconds to drive the travel time movement core to drive the watch hand to travel, and the rest time is in a dormant state to reduce energy consumption.
When the zero position identification trigger mechanism sends a zero position signal to the clock movement control MCU, namely, under the condition that the pointer is 0 hour and 0 minute, if the difference between the zero position signal and the pointer is 10 days from the last satellite time calibration, the clock movement control MCU receives a standard time signal sent by the Beidou/GPS satellite information receiving module, and updates the time information into the internal running time of the clock movement control MCU, namely, an RTC real-time clock. And then, when the movement runs to 0 hour and 0 minute, the clock movement control MCU checks whether the internal running time is 0 hour and 0 minute, if so, the movement continues to work normally, and otherwise, time compensation is carried out.
When the pointer time of the travel movement is different from the RTC time of the internal running time, synchronous operation is required, the pointer time of the movement is 0 minute and 0 minute, the RTC time is converted into a time multiple value of 30 seconds, and the clock movement controls the travel movement to clockwise advance the travel movement by the time step number of the value, namely the synchronous operation is finished.
